Compatibility/Mobile/Libraries

Mobile Frameworks and Libraries

This wiki exists to document some of the research that the Web Compat team is doing around compatibility with existing and new (mobile) libraries and frameworks (i.e., jQuery Mobile, Zepto). Feel free to add links to issues or bugs, or start a new section. The end goal is to document current compatibility with Firefox OS and Firefox for Android and advocate within Mozilla for fixes to libraries where compatibility can be improved upon.

The commitgrep tool may be useful in this line of research.
